' Application filed. November 29, 1919. Serial No. 341,352.

To all whom it may concern:

Be it known that I, ROBERT I1. CAMPBELL, a citizen of the United States,residing at I-Iagerstown, in the county of Washington and State ofMaryland, have invented certain new and useful Improvements in Footwear,of which the following is a full, clear, and exact description Iheobject of the invention is to improve the manufacture of that type offootwear in which staples are used to Secure the upper and the soletogether. Hitherto it has been customary to clench the staples on theoutside of the sole, but this results in an unsightly finish, and whenthe clenched points are worn ofi, which soon occurs, the security of thefastening is impaired.

In the present invention the staples or other metallic fastenings areclenched in the interior of the outer sole and so concealed andprotected against wear until the sole itself is practically worn out. Toaccom plish this the sole is pierced laterally from its outer edge aboutmidway of its thlckness and the piercing agent is utilized as an anvilagainst which the points of the staple are clenched and therebyconcealed within instead of in or upon the outer exposed surface of thesole, as I will proceed now to explain and finally claim.

In thelaccompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1 is aperspective view and cross section of the toe portion of a shoe. Flg. 21s a diagrammatic side elevation illustrating one means for carrying outthe invention, and Figs. 3 and 4 are respectively an end elevation and atop plan view of such mechanism.

In illustration of the invention, I have shown a portion of a sandal,but of course the invention is not limited to any particular type orstyle of footwear.

Referring to the illustration, 1 designates the upper having its edge 2turned out and connected with the inner sole 3 in any suitable way forhandling, and 4; is the outer sole. These three parts, namely, theupper, inner sole and outer sole, are connected by means of staples 5 orother metallic fastenings, driven through the out-turned edge of theupper and inner sole and clenched within the body or substance of theouter sole, instead of being driven entirely through the outer sole andclenched on the outside thereof. In order to effect this interiorclenchmg of the staples, I use a cutting tool 6 whlch, as shown in Fig.l, is driven into the edgeof the outer sole about midway of itsthickness to make an incision in the sole, and this cutting tool isthereafter used as an anvll against which the points of the staple areupset or clenched, so that these upset or clenched points are concealedwithin the interior of the outer sole and thus protected from wear untilthe sole is practically worn out. Not only is this concealment effectedby this construction, but a shoe is produced of very much more sightlyappearance than were the points of the staples clenched on the outsideof the sole.

After the staples are in place, a welt 7 may be laid over the out-turnededge 2 of the upper and secured by stitches 8, or otherwise, and thesestitches or other fastenings may extend through the welt, the out-turnededge 2, the inner sole and the outer sole, so that when the shoe isfinished it has. the appearance of a sewed shoe.

The cutting tool 6 may be of any suitable construction and operated inany suitable way, but I have shown in Figs. 2, 3 and 4. the essentialparts of the machine for this purpose. As thus shown, the cutting tool 6may be mounted in a rest 9 for supporting the shoe while being operatedupon, and this tool may be connected with a rotary cam 10 by which areciprocating motion is imparted to the tool. As the shoe is presentedstep by step for the reception of the staples 5, the cutting tool isdriven into the edge of the sole as indicated in Fig. l, and itsreciprocation arrested until the staple driving mechanism (not shown butof any approved kind) operates to drive the staple, so that its pointswill strike the cutting tool and be clenched thereon, and then thecutting tool is withdrawn from the incision made and the shoe moved to anew position to receive another incision and staple, as previouslydescribed.

The incision made is small and is effectively closed by the applicationof the welt, or in any other suitable way.

As already pointed out, by the construction described the clenchedpoints of the staple are concealed in the interior of the outer sole.

\Vhile the invention is shown and described as applied to the use ofstaples, of course, it is to be understood that other fastenings may beused and their points clenched in the same way.

Variations in details of construction are permissible within theprinciple of the invention and the claims following.

WVhat I claim is 1. An article of footwear, having an upper and an outersole, said sole having a series of independent lateral incisions equalin number to the number of the next mentioned' fastenings, and metallicfastenings inserted in the upper and engaging the outer sole and havingtheir points clenched and concealed within the interior of the outersole next to said incisions.

21 An article of footwear, having an upper provided with an out-turnededge, an outer soleprovided with a series of independent lateralincisions, and metallic fasinnings applied to the out-turned edge of theupper and having their points clenched and concealed in the lateralincisions made in the outer sole.-

3. The improvement in the art of making footwear, which consists inassembling an upper and an outer sole and providing independent lateralincisions at intervals in the outer sole made therein through the edgeof the outer sole as the work progresses, and applying metallicfastenings to the edge of the upper successively with the formation ofthe incisions and clenching the points. of such fastenings upon the toolused for mak ing said incisions and then" withdrawing the tool;

In. testimony whereof Inhave hereuntoset my hand this 24th day ofNovember A. D. 1919.

ROBERT L. CAMPBELL.
